I'm definitely going to hit you up during my build. Right now I'm making negative progress, I was originally working on it as a project for my welding class at VC, but I wanted to keep working on it while I wasn't in class so I started tacking things together with my arc welder at home. Once I started making forward progress, measuring took a backseat to getting that next piece on. Now I get to grind off a bunch of tack welds and refit the front frame and top rails.
Luckily common sense took hold before I made anything permanent, but it's still rather frustrating to have to work backwards.
